Method of forming patterned metal unit, and patterned article formed with the same

A method of forming a patterned metal unit on an article, comprising the steps of:

• providing an article that has an insulating surface;
• transferring a catalyst layer onto the insulating surface of the article, the catalyst layer including a catalytic material;
• forming a conductive metal layer on the catalyst layer by an electroless plating technique;
• and
• removing a part of the conductive metal layer and a part of the catalyst layer from the article to form a patterned metal layer and a patterned catalyst layer that constitute a patterned metal unit.

A patterned article formed with a patterned metal unit, comprising:

• an article that has an insulating surface formed with a non-planar portion;
• an adhesive layer that is disposed on said insulating surface of said article;
• a patterned catalyst layer that includes a catalytic material and that is disposed on said adhesive layer;
• and
• a patterned metal layer that is disposed on said patterned catalyst layer and that has a pattern identical to that of said patterned catalyst layer.
